WALTER R. MALCOLM, OF ALBANY, NEW YORK.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 756,867, dated April 12, 1904.

Application filed February 2, 1903.

To all whom it nuty concern:

Be it known that I, WALTER R.-MALooLM, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to lubricators adapted to be applied to the axles of locomotives, and has for its object to provide suitable mechanism whereby such axles may be constantly oiled automatically and by means of which such axles may also be specially oiled at the will of an operator from the cab of a locomotive even when in motion.

A further object of my invention is to dispense with the use of oiled waste, hemp, or other materials of a similar character which have heretofore been applied to the under surface of such axles.

In prior devices of such character it has been found that the axles when in use cause the portions of such fibrous material nearest thereto to become dry and hard, and the axles being thereby deprived of oil soon become heated and inoperative.

In the accompanying drawings, Figure 1 is a side elevation of a device embodying my invention applied to a locomotive. Fig. 2 is a vertical transverse section of a portion of my device applied to a car-axle. Fig. 3 is a vertical section taken on line 1 1 of Fig. 2.

As illustrated in the drawings, A represents a cylindrical air-chamber secured to a locomotive in any suitable manner and provided with a tube or pipe B leading to a valve chamber C, which is preferably arranged within the cab of the locomotive and provided with a valve of ordinary construction having a handle D connected therewith. The valvechamber C is 1 also provided with a tubular connection E, extending from said chamber to pipes H, which are arranged lengthwise of an open oil-chamber I, formed in a box J in line with and below the axle F, which box is Serial No. M13405 (No model.)

formed on or secured to a bearing-plate K,

adapted to bear against the under side of the axle. The pipes or tubes H are provided with perforations for the purposes hereinafter described. A tubular connection Lalso extends from the oilchamber I to an oil-cup Gr, having a detachable cap, by means of which oil may be poured into said cup and pass through the tubular connection L into the oil-chamber I, which is thereby kept constantly filled with oil. The bearing-plate K is provided with grooves or recesses is, adapted to hold lubricating material, and such plate is held in contact with the under side of the axle by means of springs M, which support said oil-box J and which are supported upon the frame 0 of the axle-bearing. The frame 0 is secured to the frame of the engine in any suitable manner and is provided with an upper. bearing-plate P, which is preferably and usually set into the upper portion of the frame 0. The upper portion of this frame is formed with a chamber or well Q, adapted to contain waste or other similar material, and an orifice may be made through the bottom of the well Q and the bearing-plate P, so that oil may be permitted to pass from said well onto the upper portion of the axle F.

When this device is in operation, oil is poured into the cups G and passes through the pipes or tubes L into the oil-chamber 1, thereby filling said chamber, pipes, and cups with oil. The cylinder A is filled with compressed air, which is permitted to pass through the pipes B into the valve-chamber C. By means of a valve of ordinary construction arranged within said chamber C the compressed air may be permitted to pass into the pipes E and the pipes H, arranged within the oil-chamber I, and through the perforations of the pipes H into the oil contained in said chamber, and thereby force such oil against the under side of the axle Whenever desired by the operator. The surplus oil applied to the surface of the axle is gathered into the grooves k of the bearing-plate K and there retained to be continuously applied to the under surface of the axle. The supply-pipe L, having the oil-cups at tached thereto, may extend to the cab of the engine, if desired, so as to be refilled by the operator from the cab.

It is apparent that the cylinder A may contain steam instead of compressed air and that such steam may preferably be used for the same purpose in cold weather, or, if desired, two cylinders may be used, one containing air and the other containing steam, each having tubular connections with the valve-chamber C similar to those shown herein, so as to enable steam or compressed air to be used at the will of the operator. It is apparent that the ordinary movement and jolting of the 10- comotive will cause the oil in the chamber I to be sloshed up against the under side of the compressed air or steam the axle maybe positively oiled by the operator in charge whether the oil-chamber I is filled or not.

I What I claim as new, and desire to secure by Letters Patent, is

The combination with an axle, of a bearingplate provided with an oil-chamber, a perforated-pipe arranged within said oil-chamber, an air-chamber, and tubular-connections provided with a valve between said air-chamber and said perforated pipe, substantially as- I shown and described.

In testimony whereof I affix my signature in presence of two witnesses. I

WALTER R. MALCOLM. Witnesses:
